A study reveals that fitness trackers and smartphone applications assist patients with heart disease in maintaining an active lifestyle.

      The humble fitness tracker might actually play a significant role in heart health.

      Fitness trackers and smartphone applications may offer benefits beyond simply monitoring your activity. A recent review published in the Journal of the American Heart Association indicated that individuals with cardiovascular disease who used smartphone apps, fitness trackers, or wearable devices were more physically active compared to those who did not utilize digital tools.

      The review analyzed 14 clinical trials with 1,057 participants diagnosed with cardiovascular conditions, including coronary heart disease, heart failure, history of heart attack, or stroke. Participants who engaged with apps or wearable devices walked nearly 1,100 additional steps each day and increased their daily moderate-to-vigorous physical activity by about four extra minutes compared to those not using these tools.

      Why even minor increases in movement are significant

      For many managing heart disease, even small improvements in activity can have a considerable impact. While cardiac rehabilitation is often recommended, accessing traditional programs can be challenging due to factors such as distance, cost, time, and mobility issues.

      In this context, smartphones and wearables have a clear advantage. They are conveniently available, offering reminders, feedback, daily step targets, motivational messages, coaching, and tracking of progress without the necessity of visiting a rehabilitation center. Some programs reviewed also incorporated gamification, quizzes, rewards, and goal assessments to maintain user engagement. Essentially, the same prompts that may annoy during a lazy afternoon could prove beneficial when integrated into a health management plan.

      This is not a miracle solution

      While the review showed improvements in daily steps and activity duration, it did not reveal significant gains in peak oxygen consumption or walking distance. Researchers emphasized the need for longer studies to determine whether such habits are sustainable over time and whether they contribute to enhanced long-term health results.

      Thus, while your fitness tracker can be a helpful support tool, it should not replace medical care, cardiac rehabilitation, medication, or professional guidance. Nonetheless, these findings strengthen the argument for the efficacy of wearable technology beyond merely tracking sleep, maintaining streaks, and estimating calories. For those dealing with heart diseases, a smartphone app or fitness tracker can encourage more proactive movement in everyday life.
